RESUMEN
OBJECTIVE: Musculoskeletal disorders (MSDs) are commonly experienced in dentistry. The objective of this study is to determine the prevalence of ergonomics and MSDs among dental professionals. MATERIALS AND METHODS: A cross-sectional survey was conducted among 170 dentists of different specialties. The questionnaire gathered information regarding demographic details, MSDs, work duration, working status, awareness of ergonomics, etc. Data was analyzed using SPSS version 15.0. Student's t-test and analysis of variance (ANOVA) test was used for comparison in mean scores. Stepwise multiple linear regression analysis was used to assess the independent variables that significantly influenced the variance in the dependent variable (pain). RESULTS: It was found that 73.9% of the participants reported musculoskeletal pain and most common painful sites were neck and back. More than half of the participants, i.e. 232 (59.3%) were aware of correct ergonomic posture regarding dental. Almost percentage of pain increased significantly with increase in age and working time. Among all specialties, prosthodontics were found to have more prevalence of MSDs. CLINICAL SIGNIFICANCE: The appearance of musculoskeletal symptoms among dental professionals was quite common. It suggested that ergonomics should be covered in the educational system to reduce risks to dental practitioners.

AIM: To treat mucogingival problems palatal masticatory mucosa is used as a donor material. This study aimed to determine the thickness of donor palatal mucosa and associations of age and gender in Indian subjects aged 14 to 60 years by direct clinical technique. MATERIALS AND METHODS: Forty systemically and periodontally healthy Indian subjects (20 males; 20 females; age range of 14 to 60 years) enrolled in this study. Under local anesthesia bone sounding technique was performed at 15 defined and predetermined points. The Wilcoxon test was used to determine the difference in mucosal thickness between the age groups and between genders. Significance of the difference between individuals of different body mass index (BMI) was assessed by independent t-test. RESULTS: With mean thickness of 2.0 to 3.7 mm, the younger age group demonstrated significantly thinner donor mucosa (mean 2.8±0.3 mm) than the older age group (mean 3.1±0.3 mm). Within the same age group though statistically not significant; males had thicker mucosa than females. From the canine to second premolar areas and in the sites furthest from the gingival margin mucosa thickness increased. When correlated with subject's BMI, in all probed sites males demonstrated significantly a thicker mucosa than females. Within each group subjects with high BMI demonstrated thicker donor mucosa. CONCLUSION: Current study showed that in both adult and young individuals, premolar and canine areas can be the right site for harvesting donor tissue. Even in young subjects subepithelial connective tissue (CT) graft can be harvested in adequate volume. Donor tissue thickness can be influenced by factors like genetics and race, which need to be further evaluated. CLINICAL SIGNIFICANCE: Premolar and canine areas serve as appropriate choice to harvest palatal masticatory mucosa. Even in young patients the volume of donor tissue available is sufficient enough to consider the subepithelial CT graft procedure. Donor tissue thickness can be influenced by factors like genetics and race, which need to be further evaluated.
